Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emissive display panels exhibit pixelation artifacts and are sensitive to ambient light, particularly in cinema environments where viewers are closer to the screen, leading to reduced image quality and inability to display high-quality stereoscopic content effectively.
Innovation Solution
Implementing light conditioning techniques such as diffusers, polarizers, and angular management systems to uniformly distribute light, reduce pixelization, and manage stray light, along with polarization-based stereoscopic viewing methods to enhance image quality and maintain consistent performance across various viewing angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If emissive display panels are used in cinema environments, then large area image content with long lifetimes can be provided, but pixelation artifacts and sensitivity to ambient light reduce image quality
Solution Approach 1:
A polarization beam splitter and waveplate system is introduced as an intermediary between the emissive display panel and the viewer. The waveplate converts linearly polarized light from alternating rows into orthogonal circular polarizations, and the polarization beam splitter directs these to different eyes, enabling stereoscopic viewing while maintaining image quality and reducing pixelation artifacts through proper light conditioning.
Solution Approach 2:
The patent changes the polarization state parameter of light emitted by the display panel. By alternating the polarization direction of adjacent rows and converting them to orthogonal circular polarizations, the system enables stereoscopic imaging while maintaining consistent image quality across different viewing conditions and reducing the visibility of pixelation artifacts.
2Adaptability or versatility
If viewers are positioned closer to the screen, then immersion is improved, but pixelation artifacts become more visible and image quality deteriorates
Solution Approach 1:
The polarization beam splitter and waveplate combination acts as an optical intermediary that conditions the light from the emissive display panel. This system maintains consistent light distribution and reduces pixelation artifacts by properly directing polarized light from alternating rows to different eyes, enabling high-quality stereoscopic viewing even when viewers are positioned close to the screen.
3Adaptability or versatility
If stereoscopic imaging is implemented, then immersive 3D content can be displayed, but system complexity and cost increase
Solution Approach 1:
The patent uses a polarization beam splitter and waveplate system as optical intermediaries to achieve stereoscopic imaging. The waveplate converts linearly polarized light from alternating rows into orthogonal circular polarizations, and the polarization beam splitter directs these to different eyes. This approach provides full-resolution stereoscopic viewing without requiring complex active shutter systems or other high-complexity solutions.

AI summary
Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources or other active sources of light. In one example, an emissive panel for a display includes an array of light sources arranged in rows and in columns that are perpendicular to the rows. The array of light sources includes a first set of light sources comprising a first light source element fabricated as a singular device and configured to transmit first light intended for a left-eye image. The array of light sources also includes a second set of light sources comprising a second light source element fabricated as another singular device and configured to transmit second light intended for a right-eye image. The transmitted first light and the transmitted second light are viewable with stereoscopic glasses as a stereoscopic image.
